Be it known that :LvDENNIS WoongSmgrn, a citizen of the United JSta'tesof Amer ca,

and a resident of l vilmette countyiof Geok and State of Illinois, havej-invented ja new and useful lmprovementlinvgonveyer vlllleehanism for PiesMaking- Machines,- of which the following is aspecification.

This invention relates Io, pie-making chines ;-wherein the various --;eperations aof making pies are performed Whl1&-lz th pie tins. are moved by a .eonveyerealong; a .definitezhorizontal path.

The main -.obj eats 7 of this invention are 'to' provide an improved formofaconveyer adapted ,to insure ;.the.- movement io f- .the plate holders val'ongzsaid path without variation therefrom, whereby the pie itinswill always be in the proper positions to accurately act .with the pie forming meehanismspato provide a conveyor 'of; the above character including an improved form ,of keenstruction coacting; withtheplate holdereaie rierstoform an endless beltyandtto provide an improved form and ---arr-an ement. of sprocket mechanism -.coacting wit .4 the endless belt %for holding the ca'rriers in proper position Y :to Lcoact awith said -;.pie ,forming mechanisms.

Fig. 3 is an enlarged side elevation of one of the plate holder carriers.

Fig. 5 is a side elevation of one of the carriers, taken from the left of Fig. 3.

The common form of conveyer for piemaking machines now in use includes a track on which the plate holder carriers are slidably supported. The carriers are connected by an 0 en link chainv arranged to form an endless Eelt for moving the plate holders along a definite path to coact with the pie-forming mechanisms. The conveyer chain heretofore used has been found to be unsatisfactory because, after considerable y i 1 identical.

*Qnlr tone-e 2 oever srhe illustrated:i n thegdrawings, but it .,wi11 be} understood thataboth ends aresubstantially in :the ens m e h i th ings, the improved form of conveyercomprises an elongated horizontally i disposed track- =1, mounted, on ;the fname struetureof the mach ne not shown) iandincludin'goan ty of plate holder carriers 4, which arec'onvnected together by a corresponding number of bars 5, and which are moved through a predetermined path by apair of driving sprocket members 6, only one ofwhich is shown. i

Each of the plate holder carriers 4 comprises a hollow post 7 having mounted there-' on oppositely disposed rollers 8 arranged to ride upon the track sections 2 and 3 for slidably supporting the carriers. Slidably supported inthe hollow, post 7, is an upright spindle 9, which carries at its upper end a plate holder 10, which is arranged to support the pie tin (not shown). The spindle 9 extends through the hollow post 7 and is normally urged upwardly by a helical spring 11 embracing thespindle 9 and bear: ing between shoulders 12 and 13formed on the spindle and post, respectively. Mounted on the lower end of the spindle ,9 and bearing against the lower end of the post 7 is a collar 14, which isadjustable for varying the position of the spindle with respect to the carrier.

Mounted on the collar14, is a roller 15, which is arranged to coact with a cam 16 formed on the track section 2 for pulling the spindle downwardly against the action of the spring 11 to facilitate the co'action' of the plate holders with the crust trimming mechanism, which is not-shownbut which is well understood in the art. Z

adjacent the upper 'end thereof, are two pairs'of spaced lugs 17 arranged to form supports forpivot pins 18 -which extend through apertures formed in theouter ends The carriers 4' of the connecting bars 5. and bars 5 are pivotally connected together in alternating arrangement to forman endlessbelt.

"The inner side 'of-the post( is formed to provide a substantially semi-cylindrical bearingsurface 19 arranged to coact with concave seats 20 formed in the outer ends of the radially disposed arms 21 of the sprocket members 6. A shoulder '22 is formed on the post "7 in position to coact withthe upper edgesof the sprocket arms 21. In order to facilitatevthe separation of the concave seats'20 of the sprocket members from the bearing surfaces 19 a block 23 is formed on the inner sideof'the post 7 to'form a shoulder located in positionto coact with the inner track sections 3130 secure the carrier against being drawn in: wardly by the sprocket arms 21 at the time each arm becomes disengaged from the post 7.

In operation, the sprockets 6 coact with the posts 7 to hold the carriers in'upright positions and drive-them through a fixed path without variation therefrom. The

improved formand arrangement of the bars this invention has been herein shown and described, itwill be understood that numerous details ofthe construction shown may be altered or omitted without departing from the spirit ofthis invention as definedby' the following claims 1. conveyer for pie making machines 1 comprising a plurality of pie plate carriers Formed on opposite sides ofthe post 7,

including upright posts and a correspondmg number of rigid bars, said upright posts and bars being 'pivotally connected together in alternating arrangement so as to form'an endless belt member movable in a predeternism, and a driving sprocket member coacting with said posts for holding said carriers in upright positions and moving them through said path.

2. A conveyer for pie-making machines comprising ahorizontal elongated track ineluding spaced rails,"an endless belt member including a plurality of plate carriers supported onsaid rails, a pair of driving sprocket members 1 including radially dis: posed arms having their outer ends formed to provide concave seats arranged to coact with said carriers for holding said carriers in upright positionsand moving them :along said rails through an endless path, and a guidebar arranged on each'of said carriers in position to coact with the inner one of said rails for retaining said c'arriers'in alinement with the axisof said path while said concave seats-arebeing disengaged from said DENNIS woon SMITH,

65 mined horizontal path to bring said carriers
